Maintenance
Cleaning
Wipe the watch regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the watch's finish and seals.
Water Resistance

This watch is rated for 50 meters (5ATM) water resistance. This means it is suitable for showering, hand-washing, and exposure to sweat. It is generally suitable for short periods of recreational swimming, but not for diving or snorkeling. Do not press any buttons while the watch is submerged or wet, as this can compromise the water resistance. Avoid exposing the watch to hot water or steam, as extreme temperature changes can affect the seals.
Troubleshooting
- Watch not displaying time: Check if the battery needs replacement. If recently replaced, ensure it was installed correctly.
- Buttons not responding: Ensure the watch is not in a locked mode (if applicable, though not a feature on this model). Try pressing buttons firmly. If unresponsive, a battery issue or internal fault may be present.
- Alarm not sounding: Verify that the alarm function is activated (alarm icon visible on display) and that the alarm time is set correctly.
- Inaccurate time: Reset the time and date as per the 'Initial Time and Date Setting' instructions. If the issue persists, the battery may be low or the internal movement may require service.
For persistent issues not resolved by these steps, please contact customer support.
